Product Description:

The MSK100D-0300-NN-M2-LG0-RNNN is a synchronous servo motor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. In automated machinery, it converts controlled electrical power from an IndraDrive amplifier into precisely regulated torque for coordinated motion on gantries, pick-and-place arms, and packaging axes. Permanent magnet excitation, internal feedback, and a concentric mechanical design help the motor maintain accurate position and speed under changing loads. This arrangement supports smooth acceleration and stable low-speed operation in applications that require repeatable motion.

Thermal management is handled by natural convection, allowing the housing to dissipate heat without auxiliary fans. The power lead enters through a left-side connector, which helps simplify cable routing in cabinets with vertical busbars. An optical feedback system using an EnDat 2.1 interface provides 2048 signal periods per revolution, giving the drive high-resolution position data. Protection against dust and water jets is confirmed by the IP65 rating, and the plain shaft accepts shrink-fit or collar couplings. The motor operates in ambient temperatures from 0 to 40 °C and is supplied without a holding brake, so load holding at standstill must come from the drive or an external clamp. Increased concentricity in the rotor helps reduce radial runout and lowers vibration during slow operation.

The motor uses frame size 100, which suits medium-power axes. Its active stack follows the D length code, increasing continuous torque over shorter versions without changing the mounting pattern. Class 155 insulation supports winding temperatures associated with cyclic overloads, while winding code 0300 sets the electrical values expected by the paired drive. A multiturn absolute encoder preserves position data through power interruptions, allowing closed-loop control to resume immediately after restart.
